Влияние допусков основных размеров проточной части центробежного насоса на разброс его основных параметров

Abstract

The article presents the method of calculating the influence of the tolerances of main dimensions of flow part of a centrifugal pump on the spread of pressure values efficiency and critical cavitation margin with the nominal feed rate. There are discussed both symmetric and unilateral deviations of sizes.

В статье представлен метод расчета влияния допусков основных размеров проточной части центробежного насоса на разброс величин напора, кпд и критического кавитационного запаса при номинальной величине подачи. Рассматриваются симметричные и односторонние отклонения размеров.
